I apologize in advance for how vague this request is. 

A few weeks ago, I came upon a paper that (if I recall correctly) proves that **the hull of a cut-and-project tiling is a fiber bundle over a torus**. This is *not* the paper by Sadun cited below, but rather it specifically deals with cut-and-project tilings. If I recall correctly, it was published in a journal of physics, or the author was a physicist. I don't recall the name being one of the "big names" in tiling spaces (like Bellisard, Forrest, Hunton, Kellendonk, Putnam, etc.). I am interested mainly in the methods that they used in the paper, and not the result itself. Sadly, the computer on which I found the paper died shortly after I found it and I lost everything related to that paper. I have no author name, no paper title, and very vague search terms to go off of in my hunt.

Does anyone happen to have any idea what paper this might be?
